Description
Technical field
The present invention relates to a kind of trestle, particularly about a kind of for the new trestle between offshore oil platform.
Background technology
Mainly adopt jacket platform in oilfield exploitation procedure at sea, particularly region oil-gas field development needs the same area is provided with numerous jacket platforms.In order to reduce the gross investment of offshore oil and gas field exploitation, between jacket platform, can related facility be shared, being usually provided with trestle between jacket platform and connecting.The jacket platform simultaneously arranging trestle connection is convenient to the dealing of personnel, the management of production operation.Because the connection of pipeline between jacket platform can be completed by trestle, can avoid by submarine laying, therefore, it is possible to significantly reduce investment.But due to the restriction of structure design intensity, the common design length of trestle is at about 50 meters.
But in actual conditions, a lot of jacket platform position is owing to being subject to drilling well position, pipe sea, periphery sea cable, other jacket platform position and the impact by many factors such as ships, and the distance therefore between jacket platform tends to exceed 50 meters.In the case, if arrange trestle in a conventional manner, then the steel using amount of trestle can be made significantly to increase, and rigidity weakens, and causes the installation difficulty of trestle.Trestle is longer, and these shortcomings are more outstanding.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of can realize long distance join between offshore platform and rigidity effective for the new trestle between offshore oil platform.
For achieving the above object, the present invention takes following technical scheme: a kind of for the new trestle between offshore oil platform, it is characterized in that: it comprises a trestle body, plural support frame and plural cable wire; Each described support frame interval is fastenedly connected in the bottom of described trestle body, and cable wire described in each and the bottom of support frame described in each are fastenedly connected and two ends are fastenedly connected at the two ends of trestle body.
Described trestle body is fastenedly connected by multiple horizontal gird, horizontal girder and the first cant beam and forms.
Support frame described in each comprises a lateral connection beam be fastenedly connected with cable wire described in each, symmetrical one end being fastenedly connected two vertical beams and multiple second cant beam on described lateral connection beam, the other end and the described trestle body of vertical beam described in each and described second cant beam are fastenedly connected, and described in two, the diagonal positions of vertical beam is fastenedly connected one the 3rd cant beam.
The cross-sectional height of described trestle body is increased to centre gradually by two ends.
The cross section structure triangular in shape of described trestle body.
The present invention is owing to taking above technical scheme, it has the following advantages: 1, the present invention is owing to being arranged at intervals with plural support frame in the bottom of trestle body, the bottom of each cable wire and each support frame is fastenedly connected and two ends are fastenedly connected at the two ends of trestle body, two distant marine jacket platforms can be connected when trestle is suitable with material, connecting length can reach more than 100 meters, and rigidity effect of the present invention is better.2, the present invention is increased to centre by two ends gradually in the cross-sectional height of trestle body, the composite bending modulus of trestle body can be increased, the cross section structure triangular in shape of trestle body, can reduce the use amount of trestle body middle cross beam, longeron and/or cant beam, maximum distortion will reduce about 20%.3, the present invention is prefabricated in place forms, and does not need at sea to connect, and can be directly fastenedly connected between two distant marine jacket platforms by conventional lifting mode.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in figures 1-4, the present invention proposes a kind of for the new trestle between offshore oil platform, it comprises a trestle body 1, plural support frame 2 and plural cable wire 3.Each support frame 2 interval is fastenedly connected in the bottom of trestle body 1, can reduce trestle body 1 in vertical distortion.Each cable wire 3 and the bottom of each support frame 2 are fastenedly connected and two ends are fastenedly connected at the two ends of trestle body 1, can prevent from, in the middle part of trestle body 1, vertical distortion occurs.
In above-described embodiment, trestle body 1 is fastenedly connected by multiple horizontal gird 11, horizontal girder 12 and the first cant beam 13 and forms.
In above-described embodiment, as shown in Figure 1 and Figure 2, each support frame 2 comprises a lateral connection beam 21 be fastenedly connected with each cable wire 3, symmetrical one end being fastenedly connected two vertical beams 22 and multiple second cant beam 23 on lateral connection beam 21.The other end and the trestle body 1 of each vertical beam 22 and the second cant beam 23 are fastenedly connected.Be fastenedly connected one the 3rd cant beam 24 (as shown in Figure 4) in the diagonal positions of two vertical beams 22, the stability of support frame 2 can be increased.
In above-described embodiment, as shown in Figure 1 and Figure 2, the cross-sectional height of trestle body 1 is increased to centre gradually by two ends, can increase the composite bending modulus of trestle body 1.
In above-described embodiment, as shown in Figure 5, the cross section structure triangular in shape of trestle body 1, can reduce the use amount of trestle body 1 middle cross beam 11, longeron 12 and/or cant beam 13.
As shown in Figure 6, during use, the mode of integral hoisting can be adopted to be arranged on fastening for the two ends of trestle body 1 of the present invention between two offshore platforms with a suspension bracket 4, form of construction work is simple.
The various embodiments described above are only for illustration of the present invention, and wherein the structure, connected mode etc. of each parts all can change to some extent, and every equivalents of carrying out on the basis of technical solution of the present invention and improvement, all should not get rid of outside protection scope of the present invention.
